What role do surface features (e.g., color) play in the establishment and maintenance of episodic representations of objects (object files)? Mitroff and Alvarez (2007) showed that stimuli that were linked by a continuous spatiotemporal history yielded object-specific preview benefits--a standard index of object files-whereas stimuli linked only by shared surface features did not. Here, it is shown that abruptly changing the features of an object that has been established on the basis of spatiotemporal history can disrupt object-specific preview benefits (Experiments 1 and 2). Moreover, under some conditions, feature match alone can give rise to the preview benefits (Experiment 3). These results indicate that surface features, as well as spatiotemporal factors, play an important role in establishing and maintaining episodic object representations.
表面特征（例如颜色）在事件相关的物体表象（物体文件）的建立和维持中扮演什么角色？Mitroff 和 Alvarez（2007）表明，具有连续时空历史的刺激物产生了特定于物体的预览优势——这是物体文件的标准指标——而仅通过共享表面特征联系在一起的刺激物则没有。在这里，研究表明，突然改变基于时空历史建立的物体的特征会破坏特定于物体的预览优势（实验 1 和 2）。此外，在某些条件下，仅特征匹配就可以产生预览优势（实验 3）。这些结果表明，表面特征以及时空因素在建立和维持事件相关的物体表象中起着重要作用。
